oceanography

Etymology

It is formed from English ocean + -ography,^[2][3] or ocean with -o- and -graphy,^[4][5][6] after German Oceanographie, now spelled Ozeanographie, in the title of a work of 1857.^[2] Etymonline and Klein see it as modelled on geography.^[7][8] Barnhart thinks French océanographie, recorded once in Middle French in 1584 but rare before 1876, may have been the model.^[4][7][2] Ocean goes back to Ancient Greek ὠκεανός (ōkeanós), and -graphy to -γραφία (-graphía), from γράφω (gráphō, “to write”).^[8] Merriam-Webster classes it as International Scientific Vocabulary.^[5]

Earliest recorded meaning

The science of the oceans: 1859, in the new edition of M. F. Maury's Physical Geography of the Sea.^[2][7][4][5] Dictionary.com dates the word to 1855–60.^[6]

Semantic evolution

The word has kept its single sense, the study of the physical and biological properties of the sea,^[2][3] and it now covers the chemistry and geology of the oceans and ocean basins as well.^[9][10] Its derivatives oceanographer and oceanographic followed in the late 19th century.^[3] Merriam-Webster lists branches such as biological, dynamic and physical oceanography,^[5] and the Oxford dictionaries compare the synonym oceanology.^[2][3]
